This is mainly an aesthetic thing, but I'm finding an interpolating quartic polynomial given some data points, so I set up a Matrix system of linear equations etc, but I want the output solution vector (i.e. the solutions for the coefficients of x, x, x, etc.) to be to 3sf. I have tried putting evalf[3](LinearSolve(A,b)); but that doesn't seem to work. Even if I change Digits, (which isn't ideal anyway as I only want output to be to 3sf temporarily) the values in the vector solution are still to 10sf.
